openSUSE and PinePhone

I am thinking of buying a PinePhone and I see there is an aarch64 .raw file available. Can anyone advise me as to how to get started on this project. I assume I have to burn the file to a micro sd.
Thanks in advance.

Thank you. I followed the instructions in the link.

Verifying the images

Every time new images are built, matching SHA-256 sums and PGP signatures accompany them. The PGP signatures verify the SHA-256 sums. These are the steps to verify our images:

    Download our public key.

    curl https://build.opensuse.org/projects/devel:ARM:Factory:Contrib:PinePhone/public_key > public_key

    Import the downloaded key.

    gpg --import public_key
    rm public_key


But then the first error.

ion@ion-Master:~/DATA/PINE> curl https://build.opensuse.org/projects/devel:ARM:Factory:Contrib:PinePhone/public_key > public_key
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

ion@ion-Master:~/DATA/PINE> gpg --import public_key
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

There is a small error in the description. The link does point to the OBS page where you can either manually download the key or simply adapt the URL an do:

curl https://build.opensuse.org/projects/devel:ARM:Factory:Contrib:PinePhone/signing_keys/download?kind=gpg > public_key
gpg --import public_key

This works.

Thanks. I had solved the problem just before reading your post. Two different versions 27.11 and 74.5.
